Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Stages 1 and 2: Bashing and Mashing. Traditionally, the process selection choice was between a conventional, welltried, threestage crushing circuit followed by ballmilling, or singlestage crushing followed by a SemiAutogenous (SAG) mill and ball mill. The latter is preferred for wet sticky ores to minimize transfer point chute blockages ...

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 9799%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.

Milling the mined ore through crushing and grinding. Ball or rod mills crush and grind the mined ore to fine particles, releasing molybdenite from the gangue (worthless rock). The grinding mills shown here reduce rocks from the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.
